Medicinal Aromatic Plants
supply chain
Different MAP species have varying
requirements for their cultivation,
resource management in the wild,
harvesting, processing and importantly marketing. The generic activities
common to most MAP supply chains
are highlighted, while the
people and organizations who may
commonly be involved in MAP supply
chains are highlighted.
In local MAP enterprises where
the market channel is short, the
same people (small-scale farmers, collectors) often harvest, process, and
sell the product to the final consumer
(see Figure 8). In longer chains it is more common for different
activities to be carried out by different
individuals, groups or organizations.
For trade to be equitable, individuals
or groups should be reasonably
compensated for their contributions
(labour, technical expertise, marketing
skills, etc.), and level of risk taken.

The variation in MAPs, from raw
fruits and food to aroma chemicals
and phyto-pharmaceuticals,
is reflected in a wide range of
different types of markets, from
bulk to niche, informal and
seasonal, to formal and regulated.
Most plants are traded regionally
and in small quantities, in rural,
peri-urban and urban settings.
For example, it is estimated
that informal trade in MAPs in
southern Africa is dominated by
500 000
traditional healers that
dispense
crude remedies and
herbal medicines from more than
1 000 plant species, to between
50 and 100 million consumers.
As such, for
small-scale
farmers and/or
collectors to move
from subsistence to trade, or
small
informal traders to move into more
regulated small-scale businesses,
various barriers to entry into
trade are often encountered, for
example
access to seedling for
planting, to the resource in the
wild and market information.
And, as activities become more
specialized further along the
supply chain, there are greater
opportunities for single traders or
small groups of traders to exert
their market power and establish
mechanisms to prevent others
entering the business. In addition, export-oriented marketing is particularly
demanding, requiring detailed
information about specific
markets, product specifications
and standards. A key challenge for
people involved in MAP activities
is to identify these barriers and,
where possible and legal, identify
ways to remove them.
Supply chain analysis can
improve understanding of how
trade networks operate, who the
main actors and organizations are
and what their specific activities
are, the different routes for trading
the MAP (which exist and could
potentially be developed), and the
skills, capacity and experience
available for successfully
engaging in trade (FAO
Diversification booklet No.12
Non-farm income from non-woodforest products).
In local, medicinal markets,
consumers mostly require fresh (with
the exception of bark), undamaged and
effective medicines. As most consumers
are from low income brackets, the
demand for value added products may
be limited, and in southern Africa in
particular, it is likely that the demand
for crude traditional medicines will
increase given the HIV/AIDS pandemic
that is giving greater use for traditional
medicines as an alternative to expensive
and often unavailable Western drugs.
Successful marketing strategies
Managing cultivation and the
natural asset base
The majority of MAPs exhibit
different natural abundance and
reproductive rates. Domestication,
cultivation and resource
management in the wild techniques
need to be mastered by small-scale
farmers and/or collectors. These
improve quality and yield. Indeed,
given the demand for a continuous
and uniform supply of MAPs and
the accelerating depletion of forest
resources, increasing the number
of MAPs species in cultivation is
an important strategy for meeting
a growing demand. Compared
to the quantity of wild harvested
MAPs, few species are currently
cultivated, and one explanation for
this may be that cultivated plants
are sometimes perceived by consumers as being of inferior
quality compared to slower growing
wild specimens which can have
higher rates of active ingredients. This is a challenge
and requires support from both
public and private institutions to
change such perceptions. This can
be carried out by informational and
promotional campaigns in local
communities to change consumers’
perceptions on cultivated MAPs.
Domestication of a previously
wild collected species requires both
substantial investment of capital,
know-how and also several years of
investigations.
Resource management plans.
For harvesting of wild MAP
resources to be sustainable, market
demand must be balanced with the
availability of the species in the wild,
and its recovery rates after harvesting.
Where commercial harvesting is
proposed or already taking place, a
species management plan is needed
in order to accurately assess impact
and establish sustainable harvesting
rates. To effectively
undertake many of the components
of a harvesting management plan will
require technical extension support.
The most useful and practical
guide available for the preparation
of a management plan, detailing
how to measure plant populations,
distribution, harvesting yields, etc.,
written specifically for supporting
communities to sustainably utilise
non-timber forest product species, is
found in Peters’ Ecological Primer
(1996).
Harvesting Techniques
The quality of MAPs and the
sustainability of extraction are closely
linked to
how plants are harvested.
Many MAPs can be harvested without
harming or killing the individual
tree or plant, but it largely depends
on what parts are harvested as to the
potential impact on the individual
plant. For example, harvesting an
entire individual plant to extract
medicinal properties can have a
detrimental impact upon a species.
Likewise, bark is frequently collected
for medicinal property extraction, and
intense and frequent harvesting often
results in ring barking of trees, which
can subsequently die. Furthermore, the time of
harvesting, and other processing
aspects such as the rate and
temperature of drying, and storage
conditions can influence the quantity
and quality of yield. The season, time
of the day harvested and technique
adopted all vary depending on
whether mature or tender parts are
harvested, and some medicinal herbs
are collected only at night. Roots
are often harvested by digging 15 to
20 cm away from the plant and by
levering the root. Exudates, such as
resin, are tapped into small containers
and transferred to plastic containers,
or recycled tin cans. In many cases,
the harvested products need to
be field-dried for short periods to remove excess moisture, whereas
more perishable products such as
flowers may need to be processed or
transported without delay.
- Processing and packaging -
Processing MAPs to add value,
stabilise properties for a longer shelflife, and improve hygiene, occurs
at different scales using a range of
technology and equipment, from
basic to very specialist. Production
facilities may range from simple units
which extract incense of essential
oils, to highly sophisticated factories
producing perfumes and medicinal
preparations.
Processing for local use may
simply involve preparation methods
such as hot and cold water extraction,
expressing the juice after crushing
the plant,
powdering dried plant material using water, oil or honey to transform a dried powder into pastes
(see Figure 10), or even fermenting
the plant matter, using a source of
sugar (FAO
Diversification booklet on No. 21
Traditional fermented foods and beverages for improved livelihoods).
As such, preparing doses from
extracts can be a suitable activity
for a small-scale enterprise, thereby
helping meet the healthcare demands
of local populations. As
medicinal compounds often naturally occur in
small quantities in a plant, processing
can require large volumes of raw
material, and therefore scaling up
or expanding an activity can have
natural resource and infrastructural
implications.
Drying is the most commonly
important processing technique for
MAPs, since many more specialized
processing technologies require
dried MAP material. Options include
shade, oven or freeze drying. Shadedrying is the lowest cost option:
plant material should be chopped
into small pieces and placed onto permeable material that allows air
flow from all directions, and dried
away from air pollution and dust.
Oven drying is faster and more
effective than shade-drying and as
such involves less risk of fungal
contamination and “aflatoxin”
infection (toxic compounds
produced by certain moulds).
However large drying ovens are an
expensive investment for a smallscale producer/processor. Freeze
drying is the most expensive and
comprehensive drying technology,
reducing plant material to very low
moisture contents, and providing
stable material with limited risk of
infection and concentrated medicinal
properties, for long periods of time.
Traditional knowledge and
processing
In the informal markets of southern
Africa, for example, MAPs are mostly
sold in raw unprocessed forms, or in
a basic processed form (chopped,
ground, or boiled extracts). Collectors
often sell plants to traditional healers
who have the knowledge to undertake
the necessary steps to prepare
medicines suitable for administering.
Packaging is usually simple, using
locally available and free products
such as newspaper wrappings,
plastic packets, and recycled glass
bottles. Commercial
pharmaceutical operations, by
contrast, produce medicines under
strict regulations concerning
processing and packaging.
Traditional knowledge is closely
tied to processing as healers can
both
identify plants with medicinalproperties, and
understand what mixtures and doses of plants can beused to treat particular ailments. Often
specific mixtures are the speciality
of individual healers. The traditional
manner of application of a MAP
should inform the type of processed
product to be manufactured from it, for
example
Bulbine (iBhucu) leaves are
traditionally administered topically to
treat skin complaints, making a cream
from them, and have never been taken
orally. Processing
can be adjusted in many cases to suit
different consumer groups, and it can
be advantageous to process a range of
types of the same product, such as the
echinacea herb used as an immune
booster which is available as a tea,
tincture, capsule, pills, and specifically
dosed syrups for children.
- Safety -
Based on the long history of MAP
usage, users of traditional medicines
accept that they are safe for human
consumption. However, the absence of
regulation of the MAP trade in aspects
such as collection, processing and
storage provides no such guarantee,
and environmental pollution,
mis-identification and adulteration can
provide further grounds for concern.
As such, in the absence of regulatory
controls, the safety and quality of
MAPs can vary considerably.
- Storage -
The shelf-life may vary for different
MAPs, and different MAPs should be
stored separately. Recommended storage
areas should be well ventilated and
designed to prevent contamination by
insects, rodents, etc., and good attention
should be paid to the cleanliness and
good maintenance of such areas. Humid
shady conditions are required for roots
and tubers for evaporative cooling, and
sawdust and straw can be used for fruits
and other more perishable products to
avoid skin damage. Spreading over
ventilated trays can be a useful way
to store dried MAPs. Storing plants,
extracts, tinctures and other preparations
may require controlled temperature and
humidity conditions or protection from
light.
- Packaging-
Packaging to avoid damage during
transport is different from packaging
to produce a final product, grade
it, or improve its presentation and
shelf-appearance. An overview
of processing technologies was
presented in Box 12. Some products
are sensitive to compression or impact
damage and bruising, and others to
contamination, and as such require individual wrapping with appropriate
mediums, such as straw, bubble paper,
corrugating medium, wooden or
plastic trays.
- Organization -
Good organization can increase
resiliency to external shocks, and access
to new markets, and is about making the
most of social assets and personal skills
for successful marketing. This can have
a positive impact on:
• Improving product quality and
making supply consistent, and
being able to diversify through
different processing methods;
• Overcoming large distances to the
point of sale and achieving more
cost-effective means of transport
and marketing;
• Being able to access and acting
upon market information and in
doing so increase the ability to
negotiate with other ‘actors’ in the
supply chain;
• Promoting the product to potential
traditional healers, consumers,
pharmaceuticals, etc.
• Improving levels of transparency
between collectors, processors and
traders to avoid the concentration of
market power in a few hands.
The ability of a group of people
or a community to organize itself to
have a positive and sustained impact
is influenced by a number of factors
including social cohesion, the existence
of other forms of organizations, and
the presence of charismatic individuals
able to motivate people to action. There
is a tendency, when MAPs are collected from private land, for the organization to take the form of a cooperative, and where the resource is collectively-owned, to lead to the development of communal organizations.
Sources of external support
can be helpful in establishing
and strengthening community
organization.
- Marketing and market
information -
Successful marketing can result
in improved income, status, and
confidence for those involved in
MAP activities, and some general
approaches include:
• Awareness of market demand by
talking to different traders and
healers about volume and price,
what consumers are purchasing,
etc.;
• Exploring different marketing
options depending on
resource access and transport
infrastructure, selling
unprocessed or processed,
directly or indirectly to
customers, traders, traditional
healers, regional wholesalers,
etc.;
• Adding value where possible,
and prolonging shelf-life of
the more perishable medicinal
products through grading or
processing into simple products,
including dried leaves, oil
extracts, etc;
• Good organization to
collaborate with other
collectors, processors, traders,
etc., and pooling stocks to
attract traders who prefer to buy
bulk quantities;
• Sharing knowledge and
experiences with other
collectors or traders and, where
necessary, the cost of seeking
external advice;
• Where possible, share resources
with other collectors, processors
or traders, and re-use and
recycle equipment, to reduce
capital investment;
• Gain familiarity of existing
markets and trading routes,
to help identify new types of
products, or niches for existing
products, which could be filled.
Successful marketing strategies
are all subject to local and
transport differences, and consumer
preferences. They may differ for
MAPs which are traded fresh, or
processed, or in bulk or as high value
low volume products. Establishing
a good relationship with traditional
healers and other buyers comes from delivering reliable qualities
and quantities of MAPs, and it
can be advisable to start modestly,
securing a small network of buyers
to whom a reliable supply can be
delivered.
- Niche marketing -
In recent years green consumerism,
coupled with a concern for
environmental conservation and a
preference for organic products, has
provided a new impetus for MAPs.
However, green marketing is a
competitive and heavily regulated
industry, and requires both specialist
knowledge and considerable
financial investment to become
certified. Requirements for any
credible certification, with which a
price premium can be placed on the
marketed product, include meeting
sustainable management criteria. Aspects of this are
inaccessible, both financially and
technically to small-scale producer
communities or organizations, and
would require external support to
undertake.
Niche marketing is therefore
relatively inaccessible to small-scale
producers, unless they are able to bulk
up the supply of their product through
some type of formal organization,
directly to a wholesaler who will pay
them a premium for their product.
In most cases it is almost certain
that producers would require both
investment and external expertise
in order to achieve recognized
certification, including Fair Trade
status, guaranteeing them access to
a premium paying niche market.
- Accessing market information -
Market information is varied but
generally related to quantity, quality
and price characteristics of particular
products in different markets, and
is essential to enter new markets
and hold onto existing ones. Good
organization can help develop social
assets and contacts with a variety of
traders and healers, and help access
more market opportunities.
Market information is only part
of the picture, and those involved
in MAP trade also need to have
the capacity to be able to act upon
it. Market information
and contacts can be less crucial
when marketing a product with high
demand, or marketing very locally.
It does however often become
more important for trade when
investments are made in processing
and grading to sell different products
at different prices. Medicinal plant
collectors can be vulnerable to
market concentration in the hands of
only one or a few traders, traditional
healers, or organizations, because of
often low formal education levels,
and remoteness from information
sources. Community organizations
and other forms of external support
can enable collectors to negotiate
improved working relationships with
existing traders, or even seek new
opportunities.
- Education, business skills and a
willingness to take risks -
Level of education can be an important
factor in determining people’s
capacity to engage in income generating activities. At collector
level it appears the informal education
and learning on the job may be more
important in ensuring a household’s
success, but for trading beyond a
local level, basic bookkeeping and
numeracy skills are often required. Personal characteristics, such
as self-confidence, a willingness and
ability to experiment, innovate, and
take risks, and in particular, attention
to detail, are all often as equally useful
qualities to have for MAP collectors
and traders. Furthermore, culture
and tradition and a community’s
indigenous knowledge can be very
important in determining success,
both in terms of MAP resource
management, and the customary
procedures for working with, and
supplying, traditional healers.
Diversification options to reduce
vulnerability
Diversified MAP activities, through
access to a range of products available for collection or trade is generally
associated with reducing vulnerability
and risk and enhancing sustainability.
Alternatively, processing the same
product can provide a range of
goods to cater for different consumer
preferences, and in turn diversifies
the market. Other ways to diversify
small-scale enterprises can include
incorporating useful by-products,
perhaps from processing raw material,
into other activities. An example
might be to use branches of suitable
species, once the leaves containing
medicinal properties have been
extracted, in agricultural mulches.
